Problems solved by technology

[0006] Although it is proposed to use a metal mask with high fineness in the formation of the cover layer, for this metal mask, there is the following problem: if the cover layer evaporates If the plating temperature is too high, the alignment accuracy will deteriorate due to the deformation caused by heat
[0009]1. The evaporation temperature is too high, and the CPL material is seriously decomposed after long-term evaporation

Abstract

The invention discloses a monoamine organic compound containing pyrenyl and benzoxazolyl or benzothiazolyl at the same time and application of the monoamine organic compound. The compound is an amine compound containing pyrenyl and benzoxazolyl or benzothiazolyl at the same time, has a shallow LUMO energy level and thermal stability, is low in evaporation temperature, has a decomposition temperature higher than the evaporation temperature, and has a low extinction coefficient and a high refractive index in the field of visible light. After the compound is applied to the OLED device as a covering layer, the light extraction efficiency of the OLED device can be effectively improved, and the angle dependence is reduced, so that the luminous efficiency of the device is improved, and the visual polarization performance is optimized.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a monoamine organic compound containing pyrenyl and benzoxazolyl or benzothiazolyl and its use as a covering layer ( CPL). Background technique [0002] Organic Light Emitting Diode (OLED), also known as organic electroluminescent device, is a technology in which organic materials emit light through carrier injection and recombination under the action of an electric field. It can convert electrical energy through organic light-emitting materials Light energy, including passive driven OLED (PMOLED) and active driven OLED (AMOLED). OLED is a new generation of display technology after cathode ray tube (CathodeRayTube, CRT) and liquid crystal display (LiquidCrystalDisplay, LCD), known as a fantastic display technology. The essence of OLED is a thin film stacked device. Theoretically, when both the anode and the cathode are transparent electrodes, the light emitted by the li...
